At its core, this smart lock leverages fingerprint recognition to offer fast, personalized entry—no more fumbling for keys or worrying about lost copies. But what truly sets it apart is its adaptability: users can also unlock using numeric passcodes or through a smartphone app when Wi-Fi connectivity is available. This multi-method approach caters to diverse household needs, whether you’re managing access for family members, guests, or service providers. With Dermum’s commitment to innovation and user experience, this smart lock isn’t just about security—it’s about simplifying your daily routine with confidence and ease.
Key Features
- Fingerprint Recognition Technology: The built-in high-precision sensor scans and verifies fingerprints instantly, granting access within seconds. Each registered fingerprint is securely stored in the device’s internal memory, allowing for quick identification without delays. This feature not only speeds up entry but also reduces the risk of unauthorized access, as fingerprints are unique and difficult to replicate. Ideal for individuals who value privacy and efficiency, the fingerprint system supports multiple users, making it perfect for families or shared spaces.
- Numeric Passcode Entry: For those moments when fingers aren’t available—or when sharing access temporarily—the integrated keypad allows users to enter a custom numeric code. You can create unique codes for different people or occasions, such as delivery personnel or houseguests, without needing physical keys. The system even supports temporary codes that expire after a set period, enhancing control over who enters and when. This flexibility makes it especially valuable for renters, Airbnb hosts, or small businesses managing visitor access.
- Smart Connectivity & Monitoring: When paired with a Wi-Fi-enabled smartphone app, the lock offers real-time monitoring and remote management capabilities. Users can check lock status, view access logs, receive alerts when someone enters, and even grant or revoke access from anywhere in the world. This feature adds an extra layer of security by keeping you informed about your property even when you’re away. It’s particularly useful for checking if doors are locked before bed or confirming that a package was delivered safely.
- Sleek Silver Finish & Durable Design: Crafted with a refined silver coating, the lock blends effortlessly into modern homes and offices. Beyond aesthetics, the construction emphasizes durability—designed to withstand daily use, varying weather conditions, and frequent handling without compromising performance. The robust materials ensure long-term reliability, while the clean lines and minimalist profile enhance curb appeal and interior harmony.
- User-Centric Interface: Despite its advanced technology, the lock features an intuitive interface with clear visual indicators and straightforward navigation. Setup is guided by step-by-step instructions, and daily operation requires no technical expertise. Large buttons, backlit keypads (in select models), and audible feedback make it accessible for all ages, including seniors and children. Maintenance reminders and battery level warnings further support consistent performance.

Benefits & Use Cases
This smart lock is engineered to meet the needs of modern living across various environments. In residential settings, it simplifies access for busy households where keys are often forgotten or misplaced. Parents can assign codes to children for safe after-school entry, while grandparents appreciate the touch-free convenience. For rental properties, the ability to generate temporary passcodes ensures security without requiring physical rekeying or lock replacement—ideal for short-term tenants or vacation rentals.
In commercial applications, such as small offices or studio apartments, the lock supports flexible access management. Managers can monitor entry times, restrict access during off-hours, and quickly revoke credentials if needed. Delivery drivers, cleaning staff, or maintenance workers can be given one-time codes, reducing friction and improving service efficiency.
The fingerprint feature also appeals to users prioritizing personal privacy. Unlike traditional locks where keys can be copied or passed around, biometric data remains securely stored on the device itself. Combined with remote monitoring, this creates a comprehensive security ecosystem that adapts to both convenience and protection needs.
Many users highlight the balance between functionality and value—especially when compared to higher-end smart locks. While some note occasional inconsistencies in build quality across units, the overall consensus praises its practicality, ease of installation, and reliable performance under normal conditions.
Important Notes
Installation requires basic tools and compatibility with standard door thicknesses (typically 1.37 inches or 35mm). Always verify your door’s specifications before purchasing. The package includes mounting hardware, user manual, and four AA batteries. Firmware updates may be available via the companion app to improve performance and add features over time.
Regular maintenance—such as gently wiping the fingerprint sensor and keypad with a dry cloth—helps preserve accuracy and responsiveness. Batteries should be replaced promptly when low-power indicators appear to avoid lockouts. Although designed for indoor and protected outdoor use, exposure to extreme moisture or temperature fluctuations may affect longevity.
While Dermum emphasizes customer satisfaction through responsive support and clear documentation, individual experiences with long-term durability can vary. Checking recent product reviews and ensuring warranty coverage is advised for extended peace of mind.

Convenience and quality.
I love this Door lock.I like that it can log who comes in and out of your apartment. You can give Each person their own fingerprint or code it came with five keys And for fobs. I ordered it in August but Iâve been using it since March and have had no issues. You can delete somebodyâs fingerprint or passcode. You can put it on passage mode where it will stay unlocked for a certain time and then lock for a certain time or a certain day, thereâs so much versatility with this door lock. I also got it with the gateway so you can do things remotely Would highly recommend. Very sturdy it didnât fit my door lock perfectly so I had to do some adjustments.. Battery life is still at 100%.The fob didnât stop working after a couple months so I need to order some new ones. Other than that, I love it for its convenience and for all of the other things that allows you to do especially being disabled and having different caregivers come in and out of my house at different times. You can lock it and unlock it via your phone as well as change passcodes or delete and add fingerprints.

Buy it without a doubt!!!
This is the first time I buy one of these, and I’m pleasantly surprised. This smart lock has so many features and ways to open, I couln’t believe. It has fingerprint reader, passcode for you and to sent to people you wanna let in without being at home, key fobs, you can use the app to open the door and also 5 sets of keys, just in case! The autolock is great for when you’re in a rush! It looks super classy, heavy, great materials and super easy to install. I even lost the installation manual, and did it anyway. Also, the customer service is great, I had a little issue, and they were super quick to respond and solve my problem! I wouldn’t doubt it, it’s a great

Customer Service has been off the chart, After sell customer service is so good.
I have been thinking about getting something like this for a while but never got the chance to do it. After hours of looking on Amazon pages, I decided to get Sifely Keyless Door Lock.The installation instruction (video) was so easy to follow, I am not anywhere near a handy man skill level and a tech savvy but was able to install, set up the app on my phone and operate the lock in about 30 minutes.But the reason for me to spend the time to write this review is this : everything (digitally) worked out beautifully from entering passcode, connecting with Bluetooth, setting up finger prints for every member of my house hold, setting up key-fob, one thing did not work properly was the physical keys, so I contacted the manufacturer via CHAT on their app, after less than 10 minutes asking me a few questions they determined it was a defect, they immediately processed the replacement to send out to me. That kind of after sale customer service was top knot, it was so good doing business with them. I highly recommend this company to everyone, SIFELY is the brand name I trust now.

Could have been a 5*…..
This lock was to install (thanks to their video) and App was easy to set up. The Sifely lock has to go on top due to the longness. The deadbolt has to go at the bottom. Your door is setup with a deeper hole on the top, which means you or a locksmith will need to chisel out a deeper hole on the bottom hole to refit your deadbolt there. Plus you’ll want to buy a different black strikeplate as this one is flimsy/ugly and silver color too boot.The only install dig is that the removable rubber backing starts to wrinkle on some edges when you start tightening the screws which kinda ruins the “tightness” of the look. You can also remove the rubber backing which easily solves that issue.Performance seems to work well. It doesn’t grab my fingerprint all the time even though I sent up my thumb in different angles and heights and saved those prints. You can always use the pinpad though which works well.The keycard works great but is too big(!) on a keychain. They should use much smaller ones and with holes as big as a key. I think I’ll buy a smaller keycard. on the internet to get what should have been included.The physical lock as a magnetic lock, which is great but didn’t include a way to open the plastic. They should have put a little indenture on the bottom to get the fingernail in there to open it. As it stands, it’s a chore taking the plastic cap off and if you do, you’ll likely mar the delicate plastic finish.To top it off, the Sifely physical key is too long! So you have a card key that’s too big and key that’s too long. Do these product designers realize how keys on a keychain look like? This objects ruin the convenience factor.Additionally, the Sifely physical lock can’t be rekeyed. Many people have ONE key to open locks from either Kwikset or Schlage, etc. But nope. You have to use their extra long key.What I’m going to do is just leave the physical key in the car. in case of emergency or a way to give energy to dead batteries to get inside. The app will advise you though when batteries are about to go out.I have this lock on my garage door coupled with the #1 rated Utec Ulock deadbolt. They both work great together.Security: This lock isn’t ANSI rated. Which means we don’t know how secure it is. But how secure are locks anyway? I saw a locksmith drill into a Schlage ANSI 1 lock in 10 seconds! So much for ratings! If a thief want to break in, he’ll go through a window or since I have glass doors, thru the door. Locks really are bubblegum –just minor deterrents. If you want real security, get a security system to line up your windows or a dog. LOL. Any security will come from the deadbolt anyways (which you should have for kickproofness).I get a lot of afternoon sun hitting this lock so it’ll be interesting to see how the electronics hold out.Despite all of my rational room for improvements, the convenience factor supercedes everything and will keep it. The other competitors also are good but also have their negativity. The electronic Schlage would be my #2 as their stuff is secure and reliable, though this product has more features.If for any reason the product fails to live up to fair level of reliability, I’ll edit this review. If you read this review after 3 years and I haven’t edited it then that means it’s still working properly. Since it’s electronic, it’s fair to hope to get 10 years. We’ll see.

Best install instructions ever
Installing kit came with little bags labeled step 1, step 2, etc.. with each bag containing required screws with instructions for each step. No need to figure out which screws go where..Wasrm easily able to setup app and gateway.Now can open door using biometrics, key pad, remote phone unlock and Alexa. Haven’t setup swipe cards as yet.This is day one after install. Will try to update in a few weeks.

After only 2 months, the fingerprint stopped working and locking mechanism failed to unlock. We’ve been left outside several times as none of the 5 different ways to get inside (not even the physical key) worked to unlock the door. Useless and a waste of money.
